Title: Gauze frame used for screen printing
Inventor: MATSUSHITA HIROMU
IPC: B41N1/24
Filed: 1988-03-31
Abstract: PURPOSE:To prevent a gauze from being cut due to the pressure contact of the gauze with corners of end parts of frame rods, by a method wherein, even if a large tension is applied to the gauze by the rotation of the frame rods in tension applying directions, the vicinity of the both ends of the frame rods is prevented from the large tension. CONSTITUTION:An opposed distance K between the edges on the side where the upper open parts of grooves 36 of frame rods 18, 22 or 20, 24 opposed in parallel face each other is reduced in the vicinity of the both ends of the frame rods. The rotatable frame rods are rotated to dispose the grooves 36 close to the opposed frame rods. Then, the vicinity of the edge parts of a gauze is disposed on the grooves 36 in tension- free states, a gauze presser plate 38 is nested into the grooves 36, and the gauze is fastened to the grooves 36 of the respective frame rods. The parts provided with grooves 36 are separated from the frame rods opposed thereto in parallel by rotating the rotatable frame rods, whereby the gauze is applied with tension to be set flat on a space part surrounded by the frame rods. At this time, because the tension of the gauze in the vicinity of the both ends of the grooves 36 is smaller than that in the other parts, the gauze cannot be cut even with the application of tension to the gauze.

Abstract: PURPOSE:To perform an exhaust operation rapidly to improve a degree of safety by a method wherein an exhaust valve is kept open until a pressure sensor detects that the pressure of laser gas inside a laser chamber reaches an atmospheric pressure, and a means exhausting laser gas inside the laser chamber is provided. CONSTITUTION:A pressure sensor 21 is a sensor which detects the pressure inside a laser chamber 3, and its detected value is added to a control device 1.

Filed: 1991-04-12
Abstract: PURPOSE:To ensure high integration by forming an isolation insulating layer which surrounds an active region of a single crystal semiconductor substrate and which has its surface lower than a substrate surface of the active region. CONSTITUTION:The width 12' of a single crystal silicon layer 27 on which active regions such as an emitter region 36A and a base region 30, etc., of a bipolar transistor are formed is made greater than an active region width 11 defined by isolation insulating layers 23A, 23B.
